In slope-intercept form, the y variable is isolated.
so,
<span>13+5y=6x
Subtract 13 on both sides.
5y=6x-13
Divide by 5 on both sides.
y=6/5 x -13/5</span>
Answer:
V = 118 in³
Step-by-step explanation:
The volume of a cone of radius r and height h is V = (1/3)(π)(r^2)(h).
In this case, the volume is V = (1/3)π(3 in)^2·(6 in), or π(18 in³)
Using 3.14 as the approximate value of π, we get V = 118 in³
Hello,
1 meter is equal to 10 decimeters.
SO, if we convert 40 meters to decimeters, we multiply 40 meters by 10 decimeters, getting 400 decimeters.
Hope this helps!

3x - y + z = 5 . . . (1)
x + 3y + 3z = -6 . . . (2)
x + 4y - 2z = 12 . . . (3)
From (2), x = -6 - 3y - 3z . . . (4)
Substituting for x in (1) and (3) gives
3(-6 - 3y - 3z) - y + z = 5 => -18 - 9y - 9z - y + z = 5 => -10y - 8z = 23 . . (5)
-6 - 3y - 3z + 4y - 2z = 12 => y - 5z = 18 . . . (6)
(6) x 10 => 10y - 50z = 180 . . . (7)
(5) + (7) => -58z = 203
z = 203/-58 = -3.5
From (6), y - 5(-3.5) = 18 => y = 18 - 17.5 = 0.5
From (4), x = -6 - 3(0.5) - 3(-3.5) = -6 - 1.5 + 10.5 = 3
x = 3, y = 0.5, z = -3.5
Answer:
y = 3
Step-by-step explanation:
9 - y = 2y
<u>Step 1: Add y to both sides</u>
9 - y + y = 2y + y
9 = 3y
<u>Step 2: Divide both sides by 3</u>
9 / 3 = 3y / 3
3 = y
Answer: y = 3
